Wausau - A new school year means new teachers, new friends, new books.

And in many school districts this year, it also means new or beefed up security systems.

Wausau Public Schools changed the way visitors get into its buildings this year.

School office staff will have to buzz people in once school hours begin.

At the front door vestibule visitors will need to explain why they're there.
Then the staff can unlock the second set of doors.

Last winter the district-wide Safety Committee looked at the security level in the school.

It decided it should add some extra measures.

"You look at what happened at Sandy Hook and those are our youngest learners and that strikes a chord for the majority of people. It certainly strikes a chord for parents. I think they can easily put themselves in that type of scenario," says Dr. Jeff Lindell of the Wausau Public Schools

That assessment began after the tragedy at Sandy Hook Elementary in Newtown, Connecticut.

A gunman entered the school and killed 20 children and 6 staff last December.
